Filed:

Jan 26, 2001

Appl. No.:

09/771046

Inventors:

Ronald D. Schlesch - Three Rivers MI
Steven O. Smith - Three Rivers MI
Charles M. Reynolds - Three Rivers MI

Assignee:

Armstrong International, Inc. - Three Rivers, MI

International Classification:

F16K 1120

US Classification:

137597, 137549

Abstract:

A station for mounting a steam/condensate responsive device in a condensate return line comprises a housing block having front and back faces, opposite end faces and top and bottom faces. The back face has a mount for removably mounting a steam/condensate responsive device. The end faces has inlet and outlet ports for connection in a condensate return line. The bottom face has a third port. An inlet valve and outlet valve are operatively interposed between and control flow between the mount and corresponding ones of the inlet and outlet ports. The inlet and outlet valves are located on and extending forward from the front face. The inlet and outlet valves are angled acutely upwardly along the front face. A compact manifold assembly mounts a plurality of such stations. A screen may be interposed between the inlet valve and mount to bar contaminant particles from the steam/condensate responsive device.

International Classification:

F22B 708

US Classification:

1221401

Abstract:

An annular tube heat exchanger immersed in a medium, such as a fluid. The heat exchanger comprises a fluid-tight combustion tube including a gas-fired radiant burner for providing a source of heat, at least one heat exchange tube including an inner tube disposed within an outer tube, the outer tube in thermal contact with the combustion tube, the inner tube being open-ended to allow the fluid to pass therethrough, and a fluid-tight combustion tube in thermal contact with the outer tube of the at least one heat exchange tube. The combustion gas from the radiant burner passes through the outer tube of the at least one heat exchange tube to cause an increase in the temperature of the fluid. By providing the maximum amount of heat transfer surface area, the annular tube heat exchanger provides a highly efficient means of increasing the temperature of the fluid.

Assignee:

Armstrong International, Inc. - Kalamazoo MI

International Classification:

F16T 130

US Classification:

137185

Abstract:

A combined inlet and outlet fitting for a fluid handling mechanism comprising a block having an inlet passage and an outlet passage having corresponding one ends adapted to be connected to the mechanism and the opposite ends thereof extending to the same one longitudinal end of the block. A coupling is attached to said one end of the block so that it can be moved arcuately relative to the block. The coupling has inlet and outlet ports connected to said inlet and outlet passages, respectively. Fastening means are provided for releasably securing said coupling in fluid-tight sealed relationship with said block.

Appl. No.:

7/581288

Inventors:

Ronald D. Schlesch - Three Rivers MI

Assignee:

Armstrong International, Inc. - Three Rivers MI

International Classification:

F16K 102
F16K 144
F16K 4110

US Classification:

251330

Abstract:

A valve apparatus comprises a valve body having a fluid passage therein including a valve seat. A valve member, having a head and stem, is movable in the body between valve open and valve closed positions determined by the proximity of its head to the valve seat. The valve member is engageable in sealing relation with a portion of the valve body between the valve seat and a valve stem packing to block fluid in the passage from contacting and leaking between the valve stem and packing. This sealing relation also serves to protect a bellows, connected between the valve member and valve body, from contact with fluid in the fluid passage.

US Classification:

410121

Abstract:

A releasable cargo anti-skid block for gripping the cargo bed of a vehicle comprises a rigid body having a cargo engageable upstanding side and a cargo bed engageable bottom.
